Isn't it generally more a case of "if the device's DMA engine isn't extremely bad designed"? There is a strong correlation between devices not supporting DMA to arbitrary locations and devices requiring a single data segment. Heck, from a design point of few there is no justification for not supporting skipping a few byte at the start of the receive. The device can easily just add two bytes of noise to make it double word aligned if necessary... VIA Rhine forever!
